Abstract (en)
[origin: EP3147063A1] The invention relates to an electrode holder (1, 2, 14) for the multichannel electrical discharge machining in electrical discharge machines. It comprises a holding element (17), a central body (15) and an electrode mounting section (19). According to the invention, the electrode mounting section (19) includes at least two clamping sections (22) for clamping electrodes (9, 10), wherein each clamping section (22) is connected, preferably via a current feeder section (21), with an own current supplying circuit (20) leading from the periphery of the electrode holder (1, 2, 14) to the respective electrode clamping section (22). The current supply circuits (20) are electrically isolated from each other by one or more insulating elements (8, 12, 25, 26, 30). Preferably the current supplying circuits (20) are allocated in or at the central body (15) of the electrode holder (1, 2, 14).
